Archives for 2008Matching waveguide radiators in antenna arrays with broadband and wide-angle scanningWe present a method for matching waveguide radiators used in wide bandwidth phased antenna arrays with wide-scanning angle. In order to achieve matching, the following parameters are used: the geometrical parameters of waveguides, the dielectric parameters of materials inside the waveguides, waveguide transformators and reactive waveguide ...

Energetic, polarization and frequency characteristics of cross-ridged circular and square waveguides as elements in phased-array antennas with dielectric covers and supports are studied. An analysis chart is introduced to aid the computation of their mode of operation with sector scanning and frequency band.

The mathematical model of a reflectarray allows introducing into a construction of each microstrip element some shunts with controllable loads. It is shown, that due to shunts it is possible to control amplitude and phase of a scattering fields.
